WHEEL FULLER AND THE LIKE.

Application filed September 4, 1924. Serial No. 735,797.

To all whom it may concern.

Be it known that I, JOHN L. MCCLELLAND, a citizen of the United States,residing at the city and county of Kalamazoo, State of Michigan, haveinvented certain new and useful Improvements in Wheel Pullers and thelike, of which the following is a specifieation.

This invention relates to improvements in wheel pullers and the like.

My improved wheel puller is especially designed for the pulling of motorvehicle wheels from their axles although desirable for use in otherrelations as in mandrel presses and the like where a threaded shaft orpart is operated upon.

The main objects of this invention are to provide an improved wheelpuller device for use on threaded axles and the like which effectivelyprotects the same and enables the separation of the wheel from the axlew1th little likelihood of injuring the threads or bending the axle.

Objects relating to details and economies of construction and operationwill definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed n the following specification. The invention is clearlydefined and pointed out in the clalms.

A structure which is a preferred embodiment of my invention is clearlyillustrated in the accompanying drawing, forming a part of thisapplication, in which:

Fig. I is a side elevation of a device embodying my invention, the samebeing shown upon an axle.

Fig. II is a transverse section on a line corresponding to line 2-2 ofFig. I.

Fig. III is a longitudinal section on a line corresponding to line 33 ofFig. II, the impact block being shown in full lines.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, my improved wheel puller comprises a bodymember 1 which is preferably cylindrical and has a polygonal portion 2adapted to receive a wrench. This is, in practice, preferably formed ofmachine steel and is case hardened, the case being quite deep, asindicated iy dotted line 3.

This body member has a. central longitudinal bore at at its inner end,the bore being threaded to correspond to the axle or shaft on which itis intended to use the device. At the inner end of this bore and axiallyaligned therewith is a recess 5 with which is seated the impact block 6,this impact block being of high carbon steel, such as tool steel. Thisblock is of such length that its outer end '7 projects centrally intothe bore 4-, overlapping the threads so that when the body member isthreaded upon a shaft. it insures contacting of the impact block wit hthe end of the shaft.

Thus arranged, the impact block receives the shock of blows when theaxle is driven from a wheel, or the thrust strains when placed in amandrel press so that the threads of the axle are not injured ordistorted, and further, the possibility of springing or bending of theaxle is minimized.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. A device of the class described comprising a cylindrical body memberhaving a polygonal portion adapted to receive a wrench and a centrallongitudinal threaded bore with a recess at the inner end thereof ofless diameter than the said bore, and an impact block seated in saidrecess with its outer end projecting centrally into the bore, thethreads of the bore extending inwardly beyond the end of the impactblock, said body member being of machine steel and having a casehardened surface, said impact member being of high carbon steel.

2. A device of the class described co1nprising a body member adapted toreceive a wrench and having a threaded here with a recess at the innerend thereof, and an im-.

pact block of less diameter than the threaded bore seated in said recesswith its outer end projecting centrally int-o the bore, said body memberbeing of machine steel and having a case hardened surface, said impactmemher being of high carbon steel.

3. A device of the class described comprising a body member having athreaded bore with a recess at the inner end, and an impact block ofharder material than the body and an impact block seated in said recessmember seated in said recess and projecting and projecting centrallyinto the bore beyond centrally into the bore in overlapping relatheinner end of the thread and in spaced 10 tion to the threads thereof.relation thereto. 5 d. A device of the class described com- In Witnesswhereof I have hereunto set my prising a body member having a threadedhand. bore with a recess at the inner end thereof, JOHN L. MGOLELLAND.
